+%description
+Using interactive visualizations, Lightbeam enables you to see the first
+and third party sites you interact with on the Web. As you browse,
+Lightbeam reveals the full depth of the Web today, including parts
+that are not transparent to the average user. Using three distinct
+interactive graphic representations — Graph, Clock and
+List — Lightbeam enables you to examine individual third parties
+over time and space, identify where they connect to your online activity
+and provides ways for you to engage with this unique view of the Web.
